The sum of two number is 18 and their difference is 6

6 and 12

Step-by-step explanation:

n + (n+6) = 18

2n +6 =18

2n = 12

n = 6

6+(6+6) = 18

6+12 = 18

18=18

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
